Patented June 6, 1933 UNITED STATES PATENT OFFECE EDWARD W. BURGESS, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO A. 0. SMITH COR- PORATION, OF MILWAUKEE, WISCONSIN, A CORPORATION OF NEW YORK PAVING. BLOCK AND METHOD OF PAVING Application filed June 15,

This invention relates to paving blocks and methods of paving.

Floors or pavements made according to the present invention are particularly adapted for use in industrial plant buildings where the floor must be periodically torn up or removed due to necessary or desired changes in the layout or plan of the building.

In the drawing wherein is illustrated a preferred embodiment of the invention,

Fig. 1 is a plan view of a portion of a floor or pavement made according to the present invention;

Fig. 2 is a section taken on a plane 1ndicated by the line 22 in Fig. 1; and

Fig. 3 is a perspective view of one of the paving blocks.

Referring to Fig. 1, the floor or pavement is made of a plurality of blocks 10 which are arranged in staggered relation. The individual blocks" are made of composite material such as concrete, cement, asphalt or similar material. In the casting of each block arcuate metal sleeves 11 of equal radii are supported within the mold around the edge portions thereof at predetermined intervals, each sleeve being so disposed that one end thereof terminates in a side of the mold and the other end terminates adjacent the top of the mold. A core is also supported in the mold at the top thereof ad acent the upper end of each sleeve in order to form a depression 12 in the upper surface of the block and within which the arcuate sleeve terminates. The sleeves are so disposed in the mold that when the finished blocks are placed in edge abutting relation with the ends of the sleeves in the sides of the block in alignment, the sleeves form a continuous arcuate dowel passage. \Vith the sleeves and cores disposed as described above, the composite material is poured into the mold embedding the sleeves and cores in the cast paving block. When the block has hardened, it is removed from the mold and the cores are removed from the depressions 12 in the tops of the blocks to give access to the sleeves.

In laying a floor or pavement made of a 1931. Serial No. 544,437.

number of these blocks, they are arranged in staggered side abutting relation with the ends of the dowel passages in the side faces of one block in alignment with the ends of dowel passages in the side faces of adjacent blocks. This is possible by reason of the fact that the arcuate sleeves have been cast in the blocks at such points that when a dowel passage of one block is in alignment with a dowel passage in an adjacent block the remaining dowel passages along the abutting sides of the two blocks will also be in alignment.

The radii of the arcuate sleeves in the paving blocks being equal, each pair of aligned sleeves forms a continuous arcuate dowel passage between adjacent blocks when the blocks are thus placed in side abutting relation. With the sleeves of the adjacent blocks in alignment, a dowel pin 13 is driven through the dowel passage formed thereby from the top of one of the blocks. The length of the dowel pin 13 is equal approximately to the combined length of the two aligned sleeves. After the dowel pin has been driven into the dowel passage in adjacent blocks, the depressions in the top of the blocks are filled with asphalt or similar plastic material to cover the ends of the sleeves and dowel pins and present an unbroken tread surface.

In removing concrete or cement floors made according to ordinary methods, the material of the floor must be broken. A floor or pavement made in accordance with the present invention may be quickly and readily laid and also quickly removed without destroying the blocks of the floor. This results in a great saving in time and material and hence expense in removing or tearing up floors in places, such as industrial plant buildings, where it is often necessary or desirable to change the layout of the building.

\Vhile the invention has been described in connection with flooring, it is equally well adapted for wall or root construction, and it is to be understood that the specific terminology used herein is not intended to be restrictive or confining and that variations and modifications may be resorted to which fairly fall within the scope or spirit of the invention as herein set forth and claimed.

What is claimed and desired to be secured by Letters Patent is:

1. A pavement composed of a plurality of blocks, each having a plurality of arcuate dowel passages of equal radii in the edge portions thereof, a dowel passage of one block being disposed opposite to a dowel passage in an adjacent block to form an arcuate dowel passage in the blocks both ends of which terminate in the surfaces, and a dowel pin disposed within the arcuate dowel passage for securing the blocks together.

2. A pavement composed of a plurality of blocks, each having a plurality of arcuate dowel passages of equal radii in the edge portions thereof, each dowel passage having one end terminating in a side face of a block and its other end terminating adjacent the top of the block, the end of the dowel passage terminating in the side face of one block being disposed opposite to a similar end of a dowel passage in an adjacent block to form a dowel passage extending through two blocks both ends of which are accessible from the top, and a dowel pin disposed within said dowel passage for securing said blocks together.

3. A pavement composed of a plurality of blocks, each having embedded in the edge portions thereof a plurality of arcuate sleeves of equal radii, each of said sleeves having one end terminating in a side face of a block and its other end terminating adjacent the top of the block, the end of the sleeve terminating in the side face of one block being disposed opposite to a similar end of a sleeve in an adjacent block to form an arcuate dowel passage bet-ween the blocks which open to the top at both ends, and a dowel pin disposed within said arcuate dowel passage for securing said blocks together.

4. In a pavement, a plurality of blocks, each having embedded in the edge portions thereof a plurality of arcuate sleeves of equal radii and depressions in the upper surface thereof, each of said sleeves having one end terminating in a side face of a block and its other end terminating in one of said depressions, the end of the sleeve terminating in the side face of one block being disposed opposite to a similar end of a sleeve in an adjacent block to form an arcuate dowel passage between the blocks and open at the top at both ends, and a dowel pin disposed within said dowel passage for securing said blocks together. a

5. In a pavement, a plurality of blocks, each having embedded in the edge portions thereof a plurality of arcuate sleeves of equal radii and depressions in the upper surface thereof, each of said sleeves having one end terminating in a side face of a block and its other end terminating in one of said depressions, the end of the sleeve terminating in the side face of one block being disposed opposite to a similar end of a sleeve in an adjacent block to form an arcuate dowel passage between the blocks and open at the top at both ends, a dowel pin disposed within said dowel passage for securing said blocks together, and filling material in said depressions for covering the ends of the dowel pin and the sleeves terminating in said depressions.

6. A composition flooring block having a plurality of arcuate sleeves of equal radii embedded at predetermined points in the edge portions thereof, one end of a sleeve terminating in a side face of said block and disposed opposite to the end of a similar sleeve in an adjacent block to form a dowel passage open at the top at both end for receiving means for securing adjacent blocks together.

7 The method of paving which comprises providing a plurality of paving blocks having arcuate dowel passages of equal radii provided in the edge portions thereof, each of said dowel passages having one end terminating in a side face of said block and the other end terminating adjacent the upper face thereof, placing said blocks in side abutting relation with the ends of said dowel passages in the side face of one block disposed opposite to similar ends of dowel passages in adjacent blocks, and driving a dowel pin through said registering dowel passages for securing said blocks together.

8. A block pavement structure comprising a plurality of blocks having arcuate dowel passageways each of which terminates in the top and side of a block, the ends of the passageways ending in the sides of the blocks being so disposed that those in adjacent blocks may be aligned to form a continuous dowel passageway both ends of which terminate in the upper surfaces of the blocks, and a dowel pin for mounting in a continuous dowel passageway extending through two blocks.

9. A block pavement structure comprising aplurality of blocks having arcuate dowel passageways each of which terminates in the top and side of a block, the ends of the passageways ending in the sides of the blocks being so disposed that those in adjacent blocks may be aligned to form a continuous dowel passageway both ends of which terminate in the upper surfaces of the blocks, said blocks having depressions in their top surfaces where the continuous passageways open, the depressions simulating countersunk openings, a dowel pin mounted in each continuous passageway eX- tending through two blocks, and a plastic material disposed in the depressions to close the ends of the passageways extending through two blocks? In Witness whereof, I have signed my name at Milwaukee, Wisconsin, this 13th day of June, 1931.
